Kathmandu, 12 Aug.: Usain Bolt regained his world
100 metres crown and restored some credibility to a sport tarnished by a
plethora of doping scandals as he scorched to gold in 9.77 seconds on Sunday,
Reuters reports from Moscow..

Fast-starting American Justin Gatlin took silver
in 9.85 with Jamaican Nesta Carter securing bronze in 9.95.

As rain fell and thunder clapped around the
Luzhniki Stadium, a pensive-looking Bolt mimed taking out an umbrella before
the start.

Disqualified from the 2011 final for
false-starting, Bolt made no mistake out of the blocks this time and although
trailing Gatlin, directly to his left, at halfway, he surged to the front at
60metres.

Gatlin, former world and Olympic champion and
twice banned for doping, stayed on his shoulder all the way to the line,
followed by Carter and two more Jamaicans Kemar Bailey-Cole and Nickel
Ashmeade.

Injured Jamaican Yohan Blake did not defend his
title from Daegu, South
Korea, while American Tyson Gay, the world's fastest man
this year, was not in Moscow
after testing positive for a banned substance.
